CDD11N Infrared Photoelectric Sensor — Diffuse-Reflection Non-Contact Proximity Switch What it does Infrared photoelectric sensor using diffuse reflection for reliable non-contact detection. Operates on 10–30 VDC and supports NPN and PNP outputs for direct connection to a wide range of controllers. Compact design built for consistent performance in industrial environments with minimal maintenance. Key benefits — why this sensor solves your problems Reliable detection across different surface colors and finishes, reducing missed reads and rework. Flexible wiring: supports both NPN and PNP outputs for straightforward integration with PLCs, relays, and other controllers. Broad supply voltage (10–30 VDC) minimizes the need for dedicated power supplies and simplifies system design. Small footprint for installation in confined spaces on conveyors, packaging machines, and robotic cells. Durable, low-maintenance operation that maintains stable performance under typical industrial conditions. Important attributes Function: Infrared diffuse-reflection non-contact proximity sensing for presence and position detection. Compatibility: Works with common industrial control systems via NPN or PNP transistor outputs; 10–30 VDC supply. Size: Compact form factor suited to tight mounting locations (saves space and simplifies layout). Performance: Fast, repeatable switching and straightforward threshold behavior to reduce setup time. Reliability: Designed for continuous operation with minimal adjustment and upkeep. Practical applications Conveyor systems: Detect part presence to trigger transfer, sorting, or downstream processing. Packaging and sealing: Confirm object position before sealing or labeling to prevent jams and product waste. Automated doors and vending machines: Provide smooth, reliable actuation and presence sensing for user interactions. Models and compatibility Product family: CDD11P (first in the family), followed by CDD11N, 40N, and 40P. Use where a diffuse-reflection, non-contact optical proximity switch is required and where integration with NPN/PNP inputs and a 10–30 VDC supply is desired. Selection tip Choose CDD11N when you need a compact infrared diffuse-reflection sensor with flexible output wiring and broad supply voltage compatibility for industrial automation and packaging applications.
